What was your favorite speaker at Axpona 2019

They were all impressive. ..some more than  others.....but 20 years ago at the Palmer house Chicago. ...my favorite speaker was the same as it was 2019....its not a rock n roll speaker per say. .....but its the only speaker that could bring me to tears...the MBL Radialstrahler 101E MKII.....there was were few empty seats in that room....maybe one day?....it was a great show ,first class. ..and all the people were very nice and friendly. ....probably the best crowd I've been around in a big event ever......
